Dynamic DNS tab

Use this tab to configure a dynamic DNS account. If the Internet interface of the UTM Firewall appliance
obtains its IP address using DHCP, Dynamic DNS can be used. A dynamic DNS service is useful when you
do not have a static IP address but still require to remain contactable by hosts on the Internet. Dynamic
DNS service providers such as TZO.com and dyndns.org can register an Internet domain name that points
to your IP address no matter how often it changes. Whenever its Internet IP address changes, the UTM
Firewall appliance alerts the dynamic DNS service provider and the domain name records are updated
appropriately.
